Question 1

How much do solar panels cost?

Accepted Answer

The cost of solar panels has reduced significantly over the years. While a system may have cost you up to £20,000 in the early days, that’s not the case anymore. So how much do solar panels cost today? The cost of an average 4kW system on an average home will set you back between £4,500-6,500. But pair that with the savings on your electricity bills and payments that you can receive from the Smart Export Guarantee (SEG), the net cost could be much less. The SEG is a payment from your energy supplier for any electricity that you don’t use and send back to the grid. Each energy supplier can set their own rate, but it must be above zero at all times. This replaces the Feed-in Tariff Scheme (FITs) which used to pay solar panel owners per kW of electricity they generated as well as that which they sent back to the grid. This was a much more lucrative scheme which saw homeowners earn back the cost of their system within a few years, but it ended in March 2019. Now, with the SEG and your savings on your electricity bills, you could save up to £330 a year – meaning you could break even within 14 years. Solar panel systems are likely to last up to 25 years, so they’re still well worth investing in. Combine that with the saving of 1.29 tonnes of carbon dioxide every year, and you’ve done your bit for the environment.

Question 2

How does solar energy work?

Accepted Answer

Solar energy comes from the sun. Solar panels absorb sunlight, and convert it into electricity. This can be used to power heating systems, lighting and appliances. You can also get solar thermal systems, which use solar energy to warm hot water.

Solar energy is a type of renewable energy, because sunlight is considered to be in unlimited supply.

Question 3

Are there different types of solar thermal panels?

Accepted Answer

There are two different types: flat plate, where lots of thin tubes carry water through a flat absorber panel, and evacuated tube, where vacuum glass tubes capture the sun’s energy directly. There is little difference in performance between the two but evacuated tube panels do more obviously extrude from the roof.

Question 4

How much energy does a solar panel produce?

Accepted Answer

How much energy a solar panel produces depends on its manufacturer and exposure to the sun. A good-quality solar panel typically has a power output of about 300 watts per hour, but this can vary from about 240 to 360 watts. How much energy your solar panel will produce per day depends on how many hours of unshaded daylight it’s exposed to.

Here’s an idea of how much energy you could expect a large commercial solar panel installation to produce in a year.

Solar panel system size, No. of solar panels, Annual electricity output

11kW, 44, 9,350kW

20kW, 80, 17,000kW

30kW, 120, 25,500kW

40kW, 160, 34,000kW

50kW, 200, 42,500kW

Question 5

How much are Tesla solar batteries?

Accepted Answer

Tesla solar batteries are some of the most expensive solar battery storage systems on the market. The Powerwall and Powerwall 2.0 are both excellent options for homes that generate a lot of electricity from their solar panels, but they might not be worth it for those that only have small solar panel systems. But exactly how much are Tesla solar batteries? Since the Tesla Powerwall 2.0 is the latest solar battery, we’ll focus on this one. With installation, you can expect to pay anywhere between £6,500 and £9,000. Other lithium-ion batteries, like SolaX or the LG Chem, will cost around £4,000, so you can see the difference in price. The benefit of the Tesla solar batteries is that they have a huge capacity. Most battery storage systems have a useable capacity of somewhere between 4-8 kWh, whereas the Powerwall has a useable capacity of 13.5 kWh. This is excellent if you have a large solar panel system that generates a lot of electricity, since you’ll be able to store all of it to use yourself rather than sending any back to the grid. However, if your system can’t generate that much, it might not be worth spending the extra money on a Powerwall. Another thing to consider is how long Tesla solar batteries last. The Powerwall 2.0’s standard warranty is 10 years, and Tesla state that it should work at at least 70% capacity for those 10 years. That’s a pretty good warranty, and Tesla says that the battery should last way beyond that. So you could have the Powerwall for around 20 years, making it seem like a better investment. Just consider whether you need such a high-capacity battery before making your purchase.

Question 6

How much do solar thermal panels cost?

Accepted Answer

How much solar thermal panels cost in total will depend on whether you’re engaging an MCS-registered installer to fit them for you or whether you’re going to do it yourself. We’d always recommend that you get a reputable company to install them for you, since they have all the relevant skills and training to do the best job. However, there are DIY solar thermal panel kits out there that have everything you need to install them. If you get an MCS-registered company to install your solar thermal panels, you should expect to spend between £4,000 and £5,000. If you buy a solar thermal panel kit online, it will set you back between £1,500 and £2,000 - but you won’t be able to claim Renewable Heat Incentive (RHI) payments. The RHI is a Government scheme that pays you for every unit of heat that you generate from renewable sources, including solar thermal panels. If you’re in a 6-person household and you installed a 6m2 system, you could earn up to £525 per year for seven years. That means that you could pay off over half your system with these payments. Plus, if you’re switching from gas fuel, you can expect to save £60 a year on your bills, but switch from LPG and it could be as much as £100 a year. So while the cost of solar thermal panels will be more upfront if you choose to get them installed by an MCS-registered professional, you could make half the cost back in RHI payments and fuel bill savings, so it’s well worth getting them fitted properly.

Question 7

Which solar battery is the best?

Accepted Answer

With so many different solar batteries on the market these days, it can be difficult to know which solar battery is the best. Luckily, we’ve picked out some of the best solar batteries on the market so you can take a look at their stats and figure out which one is best for you. Powervault 3: 8 kWh model This lithium-polymer solar battery has a useable capacity of 8 kWh and a depth of discharge (Dod) of 100%. It’s covered by warranty for 10 years. Cost: From £7,020 Tesla Powerwall 2.0 The famous Tesla Powerwall has a huge useable capacity of 13.5 kWh and also has a 10-year warranty, with a guarantee that it will work at 70% capacity during those 10 years. It’s a lithium-ion battery. Cost: From £6,500 Powervault 3: 4 kWh version This more modest solar battery from Powervault has a capacity of 4 kWh, but benefits from the same warranty length and DoD as its 8 kWh brother. Cost: From £4,470 SolaX 3.3 This more affordable solar battery from SolaX has a 10-year warranty and a good DoD of 90%. Cost: From £4,010 LG Chem RESU 6.5 LG are an up-and-coming player in the solar market and their 6.5 kWh battery is one of the most affordable on the market. Its DoD is 90% and it comes with a 10-year warranty. Cost: From £3,043 To decide which solar battery is best for you, you need to consider: The power of your solar panel system – there's no point buying a higher capacity battery if your system will never generate enough electricity to charge it How often you think you will need to charge your battery Your budget Whether you care about having the latest technology and a recognisable brand name When you’ve made these decisions, you can narrow down your choices. It’s also worth asking a few MCS-registered installers for their opinions on what they think would be best. Of course, they want to sell you whichever brand they supply, but they probably chose this for a reason. Ask them to give you a few pros and cons for the brands they recommend and see if this matches up with your research.

Question 8

Does a solar battery work in a power cut?

Accepted Answer

If you’re thinking of adding a solar battery to your home, you might be wondering whether or not it’s going to work in a power cut. If yes, then you’re not alone as this is one of the most common questions asked when it comes to solar batteries. In this post, we aim to provide you with a detailed answer to solve this concern once and for all.

The answer to this question is, it depends. The main reason why your solar batteries will usually not work or provide your home with the much-needed back up power is as a result of the several threats it poses. You should be aware that both your solar panels and battery are connected to the main grid. When a power cut occurs, your engineers will have to operate on the grid. If the solar panels or batteries are in operation at the period there’s a high chance the engineers would be electrocuted by the electricity that’s being produced. As a result of this, solar inverters are usually designed to automatically switch off once a power cut occurs. However, it should also be noted that if your solar battery possesses backup functionality, you’ll be able to make use of your solar energy in the event of a power cut. In other words, what determines if your home battery would work in a power cut is the availability or otherwise of a backup functionality.

Furthermore, you might also wish to know if your solar panels will continue to charge the battery in a power cut. Well, this depends on the type of backup system you possess. There are some more affordable batteries that are designed to automatically release their stored energy upon the detection of a power cut. And this is mostly because the battery inverter is usually smaller than the solar inverter which allows the energy from the solar inverter to the transmitted to the battery - risking an overload. However, if otherwise, then energy can continue to be transmitted to the battery until its fully charged.
